Related Questions and Answers

Q: 1. Is it possible to disable the 12v phantom power?

A: Yes. There are 4 numbered DIP switches on the back of the unit. To disengage the phantom power, simply flip the right-most switch numbered "4" into the down position, and the phantom power will turn off.

Q: 2. Does this include the power cord to the mixer?

A: The Shure SCM268 utilizes a 3 pin IEC power connection with power cord included.

Q: 3. I copied the following from the Shure manual. Would any of these setting cause over sensitive clipping/muting from my amp? Thank you Low-Cut Filter 1 - 8: Recessed screwdriver adjustment provides adjustable low-frequency rolloff (high pass) to reduce undesirable low-frequency signals. High-Frequency Shelving Filter 1 - 8: Provides level boost or cut in mid/high-frequency region to compensate for off-axis tone coloration, or for cutting high-frequency sibilance.

A: The low and high-cut settings mentioned in the manual only affect the frequency of the signals passed by the Shure SCM810 8-Channel Microphone Mixer, and would not influence factors related to volume or signal strength from the output of the mixer into an amp.

Q: 4. Can you run the SCM268 stacked or in series? Not sure of the wording. One unit into another so you can use 8 XLR inputs and one XLR output. This is for voice only.

A: I haven't tried this but I imagine you can take the mixed signal output from one unit and run it to one of the channels of a second mixer. You could still adjust the 4 channels of the first mixer but the levels would be limited by the level of the mixed signal output of that first mixer. That make sense?

Q: 5. My mics need 48v phantom power. I dont see that in the specs? Can it supply or not?

A: I use this mixer with an Audio Technica condensor mic. The mic's specs say it requires 48 volt phantom power, but it works fine on the 12 volts from this mixer. I even got an external 48 volt phantom power supply, thinking the mic would sound even better with the full 48V, but it sounds the same with 12 or 48 volts.

Q: 6. Will this work with four Shure CVB-B/O Boundary Condenser Microphones?

A: The CVB/O operating voltage is 11V - 52V of phantom power. The SCM268 will give you 12V of phantom power so this will work with 4 - CVB/O microphones.

Q: 7. Will this work for microphones to a video camcorder?

A: No it doesnt.

Q: 8. How do you listen to the city that's not playing through headphone?

A: There is no cue assign on this mixer.

Q: 9. what country is Sure made in?

A: According to the information we have, the Shure SCM-810 Country of Origin is U.S.A. Please be aware this can change over the product's production life without notice. Also please note that different product lines are manufactured in different countries.

Q: 10. Can this fit on a 4U standard rack mount carrying case.The width fits the standard measurement?

A: Yes it can.
